About

Henry M. Walker is a pioneering figure in computer science education, whose work has fundamentally shaped how programming is taught at the introductory level. His primary research areas center on curriculum development, innovative pedagogy, and the integration of hands-on learning tools in computer science. Walker’s most notable contribution is his groundbreaking use of robotics in foundational courses, as detailed in his highly cited 2012 paper, *"A C-based introductory course using robots."* This work demonstrated how Scribbler 2 robots could transform a traditional CS2 course on imperative problem solving and data structures into an engaging, active-learning experience, sparking a widespread movement to boost student interest and retention in the field. Beyond curriculum design, Walker is a strong advocate for student-faculty collaboration in course development. His 2014 paper on this model, which reimagines students as co-creators rather than passive recipients of education, has been influential in promoting active learning strategies. With over a decade of impact, Walker’s research—garnering hundreds of citations—continues to inspire educators to rethink how computer science is taught, making him a vital voice in the ongoing evolution of CS pedagogy.
